*Best value*: *China Clida 10HP Air-Cooled Chiller ₦2.8M New* – For 2 injection machines or laser.

### *Air-Cooled vs Water-Cooled Chiller*
**Air-Cooled Chiller ₦2.8M 10HP** **Water-Cooled Chiller ₦2.4M 10HP**
**Cooling** Fan blows hot air out – Like AC outdoor Needs cooling tower + water – Extra ₦1.2M
**Install** Plug + water pipes only – Easy + Cooling tower + extra pump + pipes
**Lagos Heat 35°C** Efficiency drops 15% – Needs shade Efficiency stable – Tower cools
**Water Use** No extra water Uses 500L/day evaporation
**Noise** 72db – Fan loud 65db – Quieter
**For** **90% Lagos factories – Buy air-cooled** If you already have cooling tower
*Buy air-cooled unless you have cooling tower already.*

### *What HP Chiller Do You Need?*
Machine Heat Load Chiller HP Needed Water Temp
**Laser Cutting 1.5KW** 5KW 3HP 20°C
**Laser Cutting 3KW** 10KW 5HP 20°C
**Plastic Injection 150T x1** 15KW 5HP 10°C
**Plastic Injection 250T x1** 25KW 10HP 10°C
**Plastic Injection 250T x2** 50KW 20HP 10°C
**Blow Moulding 1L x1** 20KW 8HP 10°C
**Chemical Reactor 500L** 30KW 12HP 5°C
**CNC / Spindle** 3KW 2HP 20°C
**Food / Beverage Cooling** 20KW 8HP 5°C
*Rule: Chiller HP = Machine heat KW / 2.6. Always add 20% margin. If machine is 25KW, buy 10HP (26KW), not 8HP.*

### *10HP Chiller – What It Can Run*
Load Can 10HP Chiller Run?
**1x Injection 250T** ✅ Yes, perfect
**2x Injection 150T** ✅ Yes
**1x Laser 3KW + 1x Laser 1.5KW** ✅ Yes
**2x Injection 250T** ❌ No – Need 20HP
**1x Blow Moulding + 1x Injection** ⚠️ Borderline – Need 15HP
### *Power Needs – 10HP Chiller*
Item 10HP Chiller
**Compressor** 7.5KW
**Pump + Fan** 2.5KW
**Total** 10KW = 20A 380V
**Breaker** 32A 3-phase
**Cable** 6mm² 4-core
**Generator** Need 25KVA min for 10HP chiller
**AVR** 20KVA AVR ₦450k if NEPA low – Chiller trips on low voltage
*Chiller draws 20A continuous – If NEPA drops to 320V, compressor overheats. Use AVR.*

### *Test Before Buying Used*
1. *Run to 10°C*: Must reach 10°C in 20 mins from 30°C. If 45 mins, gas low or compressor weak
2. *Check compressor amps*: 10HP compressor must draw 14-16A. If 20A+, compressor dying
3. *Leak*: Soap water on all joints – No bubbles. Gas leak = ₦120k refill
4. *Water pump*: Must pump 6 m³/hr. If weak, pump impeller worn
5. *Tank rust*: Open tank, if brown rust, heat exchanger may be leaking

### *Key Tips*
1. *Don't use borehole water direct*: Scale kills chiller in 3 months. Use RO / treated water + inhibitor ₦20k
2. *Shade*: Put air-cooled chiller in shade, not direct sun – Lagos sun 35°C + chiller heat = 50°C, chiller trips
3. *Airflow*: Keep 1m space around chiller – No wall blocking fan
4. *Clean condenser*: Blow dust weekly – Lagos dust blocks condenser, pressure rises, compressor trips
5. *Insulate pipes*: Insulate chilled water pipes – Bare pipe loses 20% cooling, condensation drips
6. *Backup*: If factory 24hrs, buy 2x 10HP, not 1x 20HP – If one fails, other keeps 50% production

*Bottom line*:
For 1x injection 250T / laser 3KW / blow moulding → *China Clida 10HP Air-Cooled Chiller ₦2.8M New* + *AVR 20KVA ₦450k + Pipes ₦80k* = *₦3.33M ready* – Cools to 10°C, runs 8hrs/day
For 2x injection 250T → *China Clida 20HP Air-Cooled Chiller ₦5.2M*

What are you cooling – Plastic injection, laser cutting, blow moulding, chemical, or food? And how many machines? And what water temp do you need – 5°C, 10°C, or 20°C? I’ll tell you exactly what HP chiller you need so you don’t buy oversize that wastes ₦500k/month power or undersize that can’t cool.
